Shooting skills of Canon G 12 camera

Canon PowerShot G 12 digital camera is a professional product, which is the best among portable digital cameras in terms of design and imaging quality. Let's take a look at the usage skills of Canon 7d camera. After reading this article, maybe your questions will be answered.

Shooting skills of Canon G 12 camera

Neutral gray filter

ND neutral gray filter may be no stranger to friends who like photography. It provides a dimming function for the camera, so that we can shoot at a lower shutter speed, which is often used when shooting streams, waterfalls and other subjects. The G 12 camera also has a built-in medium gray filter. If necessary, you can turn on the function of ND medium gray filter, which can reduce the light by two steps.

Fisheye effect

Fisheye effect is a very interesting shooting function provided by G 12. It makes the central area of the picture stand out through spherical deformation through in-machine calculation, making the center of the picture more interesting.

Miniature landscape effect

Miniature landscape effect is a very familiar function. By blurring the part of the picture, the visual effect of shooting the model with a shifting lens is created. At the same time, the camera also improves the image saturation and creates a similar model effect.

The above functions are all G 12 or practical or interesting functions, among which ND neutral gray filter function is very suitable for taking scenery photos and can provide effective assistance when long exposure is needed. The fisheye function is a function suitable for shooting animals or distorting the subject. The miniature landscape function now has a group of supporters and is an interesting shooting function.

Canon G 12 evaluation

1.HS system realizes purer and higher image quality.

The HS system of PowerShot G 12 adopts high-sensitivity CCD image sensor, and the effective pixel is about100000. By controlling the number of pixels at the level of 6.5438+million, the area of a single pixel is enlarged, thus improving the cost performance and reducing the noise on the image sensor. As for the image processor, it is equipped with DIGIC 4 digital image processor used by some EOS digital SLR cameras, which can not only clearly present the outline of details, make the image clear, but also present high-saturation gorgeous colors at high ISO sensitivity. PowerShot G 12 improves the noise reduction algorithm, and the definition is higher when shooting at high ISO sensitivity. To sum up, we can see that the HS system itself is constantly developing.

2. HDR (High Dynamic Range) mode with wide dynamic range is obtained by image synthesis.

In HDR (High Dynamic Range) mode, you can continuously take three images of underexposed, normal and overexposed by pressing the shutter button once, and the three images are combined into 1 image in the camera. In the scene with strong contrast between light and dark, the missing dark parts of the image are filled with overexposed bright images, and the overflow highlights are filled with underexposed dark parts, so that the image can obtain a wide dynamic range. Because HDR (high dynamic range) mode needs to synthesize three images, it is suggested to fix the camera on a tripod to shoot, so as to obtain a better effect.

3.Digic 4 image processing engine system and dual IS image stabilizer.

PowerShot G 12 adopts Digic 4 image processing engine system, which brings better noise control performance and can obtain clear and beautiful images to a greater extent. The dual IS image stabilizer is equipped with an angular velocity sensor that can detect tilt jitter and an acceleration sensor that can detect translation jitter. The camera will drive the compensation optical lens group according to the jitter detected by each sensor, and compensate the picture jitter accordingly. In this way, the camera can cope with the jitter in various scenes from close-range shooting to long-range shooting. Dual IS image stabilizer was developed by Canon and first installed in? EF 100mm f/2.8L is a USM macro? In front of the camera. PowerShot G 12 is the first model to apply this technology to G series digital cameras.

4. The subject can be tracked and focused automatically.

Is PowerShot G 12 new? Automatic tracking and focusing? Function. Whether the subject suddenly approaches or enlarges, the autofocus frame will be adjusted according to the size of the subject in the composition, so as to keep tracking and focusing on the subject.

In structural design, G 12 not only has full manual control and semi-automatic mode setting, but also adds a brand-new front-end control dial, which provides a fast and convenient operation mode during shooting. For example, the front wheel can be used to adjust the aperture, white balance or shooting mode.
